61/**
62 * The BreakIterator class implements methods for finding the location
63 * of boundaries in text. BreakIterator is an abstract base class.
64 * Instances of BreakIterator maintain a current position and scan over
65 * text returning the index of characters where boundaries occur.
66 * <p>
67 * Line boundary analysis determines where a text string can be broken
68 * when line-wrapping. The mechanism correctly handles punctuation and
69 * hyphenated words.
70 * <p>
71 * Sentence boundary analysis allows selection with correct
72 * interpretation of periods within numbers and abbreviations, and
73 * trailing punctuation marks such as quotation marks and parentheses.
74 * <p>
75 * Word boundary analysis is used by search and replace functions, as
76 * well as within text editing applications that allow the user to
77 * select words with a double click. Word selection provides correct
78 * interpretation of punctuation marks within and following
79 * words. Characters that are not part of a word, such as symbols or
80 * punctuation marks, have word-breaks on both sides.
81 * <p>
82 * Character boundary analysis allows users to interact with
83 * characters as they expect to, for example, when moving the cursor
84 * through a text string. Character boundary analysis provides correct
85 * navigation of through character strings, regardless of how the
86 * character is stored. For example, an accented character might be
87 * stored as a base character and a diacritical mark. What users
88 * consider to be a character can differ between languages.
89 * <p>
90 * The text boundary positions are found according to the rules
91 * described in Unicode Standard Annex #29, Text Boundaries, and
92 * Unicode Standard Annex #14, Line Breaking Properties. These
93 * are available at http://www.unicode.org/reports/tr14/ and
94 * http://www.unicode.org/reports/tr29/.
95 * <p>
96 * In addition to the C++ API defined in this header file, a
97 * plain C API with equivalent functionality is defined in the
98 * file ubrk.h
99 * <p>
100 * Code snippets illustrating the use of the Break Iterator APIs
101 * are available in the ICU User Guide,
102 * https://unicode-org.github.io/icu/userguide/boundaryanalysis/
103 * and in the sample program icu/source/samples/break/break.cpp

611 * and replaces them with references to the new.
